9.99 * (1-(15/100)) = 8.49

8.49 * (1+(6/100)) = 9.00

10-9 = 1

He will give you $1.
Hope this helps! :)

Solve 8x+c= k for x.
Anon25 [30]

Answer:

x =  (k-c)/8

Step-by-step explanation:

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x =  (k-c)/8

(10x2)x3=10x(2x3)<br><br> A. True<br><br> B. False
Vesna [10]
Solve both sides and check to see if the solutions match.
(10 • 2) = 20
20 • 3 = 60
Now check the other side:
(2 • 3) = 6
10 • 6 = 60
Compare the solutions:
60 = 60
This is true, so the answer is A. True.

Which equation is the Gizmo using to find the x coordinates​
wlad13 [49]

Answer:

The correct answer is C. (0,10).

Step-by-step explanation:

The polar coordinates are defined in terms of r and θ, where r is the distance of the point from the origin and θ is the angle made with the positive x-axis.

To convert from Polar Coordinates (r, θ) to Cartesian Coordinates (x, y) apply the following conversion formulas:

                                                      x = r\cos \theta \\y = r\sin \theta

We know that r=10 and \theta = 0.5\pi

So, the cartesian coordinates are,

x=10\cos \left(0.5\pi \right)=10\cos \left(\frac{1}{2}\pi \right)=10\cos \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \cos \left(\frac{\pi }{2}\right)=0\\\\x=10\cdot \:0\\x=10

y=10\sin \left(0.5\pi \right)=10\sin \left(\frac{1}{2}\pi \right)=10\sin \left(\frac{\pi }{2}\right)\\\\\mathrm{Use\:the\:following\:trivial\:identity}:\quad \sin \left(\frac{\pi }{2}\right)=1\\\\y= 10

The correct answer is C. (0,10).
